vis.fs.surface: Visualize fs.surface mesh

In dfsp-spirit/fsbrain: Managing and Visualizing Brain Surface Data

Visualize fs.surface mesh

Description

Render a mesh. All mesh formats supported by the *freesurferformats* package are supported, including OFF, PLY, OBJ, STL, and many more.

Usage

vis.fs.surface(
  fs_surface,
  col = "white",
  per_vertex_data = NULL,
  hemi = "lh",
  makecmap_options = mkco.seq(),
  ...
)

Arguments

fs_surface	an fs.surface instance, as returned by function like subject.surface or read.fs.surface. If a character string, it is assumed to be the full path of a surface file, and the respective file is loaded with read.fs.surface. If parameter 'hemi' is 'both', this must be a hemilist. A single rgl::tmesh is also fine.
col	vector of colors, the per-vertex-colors. Defaults to white. Must be a single color or one color per vertex. If parameter 'hemi' is 'both', this must be a hemilist.
per_vertex_data	numerical vector, per-vertex data. If given, takes precedence over 'col'. Used to color the mesh using the colormap options in parameter 'makecmap_options'. If a character string, it is assumed to be the full path of a morphometry data file, and the respective file is loaded with read.fs.morph. If parameter 'hemi' is 'both', this must be a hemilist.
hemi	character string, one of 'lh' or 'rh'. This may be used by visualization functions to decide whether or not to show this mesh in a certain view.
makecmap_options	named list of parameters to pass to makecmap. Must not include the unnamed first parameter, which is derived from 'measure'. Should include at least a colormap function as name 'colFn'.
...	extra parameters to pass to vis.coloredmeshes.

Value

see vis.coloredmeshes

Note

This function can be used to visualize arbitrary triangular meshes in R. Despite its name, it is not limited to brain surface meshes.
